If you want to avoid postback while replacing the image in OnClick event of a button or image button.

You can use Update Panel along with Async Postback Trigger.

Your code structure will be like this.

XML

<asp:UpdatePanel ID="UpdatePanelID" runat="server">
   <ContentTemplate>


            //YOUR Image Button/Button

   </ContentTemplate>
                <Triggers>
                         <asp:AsyncPostBackTrigger ControlID="Button/imageButtonID" EventName="Click" />
                </Triggers>
 </asp:UpdatePanel>

Hope it will help.. :)

my html code :

C#

  <asp:updatepanel id="UpdatePanel2" runat="server" xmlns:asp="#unknown">
    <contenttemplate>
        <div>
            <asp:textbox id="editor" runat="server" cssclass="bord" width="40%" maxlength="80">
                ValidationGroup="1" TabIndex="1"></asp:textbox>
        </div>
<pre lang="vb"><asp:Button ID="Button1" runat="server" Text="send " OnClick="Button1_Click"
              CssClass="btn" Width="10%" ValidationGroup="1"/>

align="center">
<asp:imagebutton id="ImageButton1" runat="server" imageurl="~/yahoo/1.gif" onclick="ImageButton1_Click">
<asp:imagebutton id="ImageButton2" runat="server" imageurl="~/yahoo/2.gif" imagealign="Middle">
OnClick="ImageButton2_Click" />

<triggers> <asp:asyncpostbacktrigger controlid="ImageButton1" eventname="Click">

The labels will show you the contents of the TextBox

C#

 public string chg(string s)
        {
           
            s = s.Replace("[a]","<img src="yahoo/1.gif">");           
            s = s.Replace("[b]", "<img src="yahoo/2.gif">");
   return s;
        }
label.text=user + ":" + chg(editor.Text.ToString());
</img></img>

I was on a updatepanel the client from the server host, but you do not

Do not use "Add Solution" Option to post any question or comment.

Rather use "Have a Question or Comment?" option.
